Petrology, geochemistry, sulphide and platinum-group element mineralization of the Geordie Lake intrusion, Coldwell Complex, Ontario
PGE-bearing Geordie Lake intrusion is located in the north-central region of the Coldwell comples near the town of Marathon.
Assimilation of basic xenoliths within centre 3 syenites of the Coldwell Alkaline Complex, Ontario
This thesis describes the occurence, mineralogy and assimilation of basic Kenoliths hosted by Centre 3 syenites. Field work ‘was earned out in two locations, one in the vicinity of Neys/Ashburton and the other a ...
Deformation of layered rocks near the Wawa-Quetico subprovince boundary / by David Lawrence Nicol
A supracrustal sequence of rocks near Manitouwadge, Ontario consists of metavolcanlc rocks, Including pillow lavas, banded iron formation, amphibolite, and a quartzofe1dspathic hornblende-blotite gneiss. This rock has ...
Stratigraphy, structure and metamorphism of Archean rocks at Rainy Lake, Ontario
The rocks of the Rainy Lake area have been deformed during three distinctive episodes. Minor structures provide the geometry which characterizes each episode. The youngest structures include regional faults, a crenulation ...
Structure and magnetic fabric of the Quetico metasedimentary rocks in the Calm Lake - Perch Lake area, near Atikokan, Northwestern Ontario
The Quetico metasedimentary rocks are the metamorphosed equivalents of a turbidite sequence, comprised of a repetative interstratification of sandstones and mudstones. The rocks are metamorphosed to lower greenschist ...
Geology of sulphide-facies iron-formations and associated rocks in the lower Steel River-Little Steel Lake area, Terrace Bay, Ontario
The Lower Steel River - Little Steel Lake area is located about 25 km east of Terrace Bay, Ontario. Seventeen iron-formations were investigated within this metamorphosed Archean volcanic and sedimentary terrain, which ...
Geology and alteration associated with the Hamlin Lake VMS system, Shebandowan Greenstone belt, Northwestern Ontario, Canada
The Hamlin Lake area is located approximately 120 km southwest of the City of Thunder Bay, Ontario within the Shebandowan greenstone belt of the Wawa Subprovince, Superior Province. The purpose of this study was to understand ...
Study of the third dimension in the Thunder Bay silver veins : fluid inclusion and stable isotope results
"Historic drill core from the Shuniah Mine and more recent drill core from the Keystone and Porcupine Mines have provided the basis for a study of these past silver-producing veins as a function of depth. Precipitation was ...
Magnetic fabrics and boundary structure at the Quetico - Shebandowan subprovince boundary, near Kashabowie, NW Ontario
The Quetico metasedimentary subprovince and the volcanic-plutonic Shebandowan belt to the south meet along an east-west steeply dipping boundary that is believed to have been affected by dextral transpressional deformation. ...
Theoretical and experimental investigation of pressure solution
Consideration of the existing thermodynamic theory of pressure solution (PS) shows that this theory is applicable to the development of PS structures as well as to local grain-scale diffusive transfer. Local precipitation ...
